Definitions

  • a structure wherein the coating liquid is circulated through a return pipe 6 from the coating liquid application mechanism 4 can be adopted as required.
  • the coating liquid 2 is circulated in the tubular body 10 of the charge supply unit 7 and a high voltage is applied to the electrode 11, a charge is induced in the tubular body 10 and is given to the coating liquid 2 circulated in the tubular body 10 and the charge of the coating liquid 2 is erased or the coating liquid 2 is charged to an opposite potential.
  • a coating liquid is poured into the dip coating tank 32 and the coating liquid storage tank 3 and is circulated by the pump 36 via the piping 5 and the return pipe 6.
  • the material of the smoothing member 30 is not limited if it has resistance to a coating liquid; an elastic material having flexibility is suitable and a sheet of rubber, plastic, or metal such as copper, aluminum, phosphoric bronze, or stainless steel can be used. It is particularly desirable to make a structure having rubber elasticity with a recess produced upon reception of a local press pressure.
  • the smoothing member contact face to the coating liquid 30 preferably the rigid material is thinned and is backed with an elastic substance.
  • Metal sputtered, application of hardening type conductive paint, a laminate or weave of a conductive sheet or film, or the like can be adopted as the method of making the surface conductive.
  • Fig. 10 shows an example of a blade using conductive foamed polyethylene (resistance value 150 k ⁇ cm), in which case the blade can be grounded via a piano wire 40.
  • the substrate 15 and the smoothing member 30 move relatively; preferably the smoothing member 30 is inclined in a direction in which the substrate 15 comes off the smoothing member 30, and is brought into contact with the substrate 15.
  • Used as a blade for the method is basically a similar blade to that used for the above-described blade grounding method.
  • An aluminum cut tube (30.0 mm in outer diameter, 28.5 mm in faucet part inner diameter, and 260 mm long) is used as a substrate.
  • a flange is attached to the aluminum substrate and an internal expanding collet chuck of a substrate rotation mechanism is inserted into a flange hole.
  • a gear motor of the substrate rotation mechanism is driven for rotating the aluminum cut tube at 200 rpm.
  • the smoothing member (blade) is made 50 mm long and 25 mm wide and a polyethylene tube with a flange is made to pierce an upper portion slightly from the center of the smoothing member. The blade touches the aluminum cut tube at a position of about 45° and comes in contact with a coating liquid spout port at a position of about 60°.
  • Example 3 The same aluminum tube 15 as Example 3 is held and rotated in a similar manner to that in Example 3.
  • Two piano wires each 0.6 mm ⁇ are inserted almost to the tip of conductive foamed polyethylene 15 mm wide, 100 mm long, and 10 mm thick, which is fixed to the nozzle base with the piano wires sandwiched between metal plates and is grounded.
  • a cyano compound shown in the following formula (3) 1.5 parts by weight of a cyano compound shown in the following formula (3), and 100 parts by weight of a polycarbonate resin (Mitsubishi Kagaku (kabu) Nobarex 7030A) are dissolved in a mix solvent of 500 parts by weight of 1,4-dioxane and 500 parts by weight of tetrahydronfuran to produce a coating liquid for an electrophotographic photosensitive charge transport layer.
  • a mix solvent 500 parts by weight of 1,4-dioxane and 500 parts by weight of tetrahydronfuran
